sinaViolinBoxPlot is a versatile MATLAB function for visualizing grouped data distributions. It combines the strengths of three common plot types:
  • Violin plots using KDE for smooth density estimation
  • Sina plots for jittered scatter points proportional to local density
  • Box plots showing Q1-Q3, median, and optional mean
The function also provides an automatic statistics panel for each category, showing key descriptive statistics in a compact, readable format. It is designed to handle large datasets efficiently, works within subplots or tiled layouts, and allows fine-tuned control over colors, transparency, marker styles, and widths.
Key Features:
  • Combine violin, Sina, and box plots in a single plot
  • Optional mean, median, and Q1-Q3 display
  • KDE-based density estimation with adjustable bandwidth
  • Scatter jitter methods: density-based, uniform, or none
  • Fully customizable color, transparency, and line properties
  • Stats panel per group showing n, mean, stdev, median, quartiles, min, max
  • Compatible with subplots and tiled layouts
  • Handles empty categories gracefully
  • Suitable for large datasets (>1e5 points)
Example Use Case:
Visualize four distinct distributions simultaneously: uniform, Gaussian, Poisson, and bimodal, with clear statistical summaries and density-based scatter points.
